For you guys who clean solar panels as well as windows what brushs do you use for solar panels, Are they different from w.c brushs? Also poles, I understand I need a much bigger pole, and depending on the size of the house depends on the length of the pole, but could anyone recommend a pole for the heights needed, I don't want to invest, rock-up to a house the pole don't reach and I have to buy another one. I would feel a size around 40-50ft would be playing it safe, I don't mind spending £300-£400 on this particular peice of equipment, as long as dont have to spend more money few months later on another high building/solar panel pole. but this doesn't include price of brush either. Many many thanks everyone, I promis once I have all my kit and starting up I will leave you all be lol. Regards!
